Electronic correlation in nanoscale junctions: Comparison of the GW approximation to a numerically exact solution of the single-impurity Anderson model
Xin Wang, Catalin D. Spataru, Mark S. Hybertsen +1
The impact of electronic correlation in nanoscale junctions, e.g. formed by single molecules, is analyzed using the single-impurity Anderson model. Numerically exact Quantum Monte…
Calculation of DOS-Dependent Channel Potentials in FETs in the Saturation Condition
Woo-young So, David V. Lang, Arthur P. Ramirez
We calculated functions for the potential, Vch, in the channel of a field effect transistor with various densities of the localized states (DOS) by using a device simulator. In the…
Digital resonance tuning of high-Q/Vm silicon photonic crystal nanocavities by atomic layer deposition
Xiaodong Yang, Charlton J. Chen, Chad A. Husko +1
We propose and demonstrate the digital resonance tuning of high-Q/Vm silicon photonic crystal nanocavities using a self-limiting atomic layer deposition technique. Control of reson…
Appearance of ferroelectricity in thin films of incipient ferroelectric
Eugene A. Eliseev, Maya D. Glinchuk, Anna N. Morozovska
The consideration of size-induced ferroelectric-paraelectric phase transition for conventional and incipient ferroelectrics thin films with perovskite structure was carried out in…
